Passenger Rail Train to Train Impact Test Volume II: Summary of Occupant Protection Program

On January 31, 2002, a train-to-train collision test was conducted involving a cab-car-led consist with three coach cars, all of conventional design, and a trailing locomotive traveling at 30 mph into a stationary locomotive coupled with two ballasted freight cars. The objective of this test was...

Single Passenger Rail Car Impact Test Volume I: Overview and Selected Results

On November 16, 1999, at the Transportation Technology Center in Pueblo, Colorado, a test was conducted of a single rail passenger car colliding with a fixed wall at 35 mph. The car was instrumented to measure (1) the deformations of critical structural elements, (2) the vertical, lateral, and...

Passenger Rail Two-Car Impact Test Volume II: Summary of Occupant Protection Program

Two full-scale impact tests of rail cars fitted with seat/occupant experiments were conducted at the Federal Railroad Administration’s Transportation Technology Center located in Pueblo, Colorado. The first test was conducted on November 16, 1999, with a single rail car that was impacted against a...

Single Passenger Rail Car Impact Test Volume II: Summary of Occupant Protection Program

A test in which a single rail passenger car was crashed into a fixed wall at 35 mph was conducted at the Transportation Technology Center on November 16, 1999. The car was instrumented to measure (1) the deformations of critical structural elements, (2) the vertical, lateral, and longitudinal...

Crashworthiness of Passenger Trains Safety of High-Speed Ground Transportation Systems

The results of analyses conducted to determine the effectiveness of structural and interior train design strategies in protecting occupants during collisions are presented. Structural design approaches considered include the conventional design approach of requiring a uniform minimum...

Crashworthiness Testing of Amtrak’s traditional Coach Set Safety of High-Speed Ground Transportation Systems

Tests have been conducted on Amtrak’s traditional passenger seat to evaluate its performance under static and dynamic loading conditions. Quasi-static tests have been conducted to establish the load-deflection characteristics of the seat. Dynamic tests of selected collision conditions have been...

Methodology for Initial Assessment of Spectrum Requirements and Required Numbers of Base Stations in a Multi-railroad, Dense Traffic Area

This report is intended to provide a methodology for performing an initial assessment of spectrum requirements related to deployment of a 220 MHz RF network for handling of Positive Train Control (PTC) messaging in a multi-railroad, dense traffic area. It also identifies how to determine the number...

Pilot for Rail Passenger Cab Cars

The results of this Federal Railroad Administration (FRA)-funded Small Business Innovative Research (SBIR) project indicate that cab car-led trains are no more likely to derail than passenger locomotive-led trains, when involved in grade crossing accidents. The performance of cab cars in...
